What's the fastest: eSATA over ExpressCard adapter, or over USB 2?
I am considering buying an ExpressCard-based eSATA controller to access an external hard disk (1TB). However, this hard disk is also already available using simple USB 2 cable. Is it worth to buy such adapter to have better performance ? Is such eSATA controller's performance comparable to the one built-in my laptop ? Is there a PCMCIA-based eSATA controller that's better than its ExpressCard equivalent ? I plan on booting a Linux server from this hard disk.
